Abstract: |
A rich literature shows that early life conditions shape later life outcomes,
including health and migration events. However, analyses of geographic
disparities in mortality outcomes focus almost exclusively on
contemporaneously measured geographic place (e.g., state of residence at
death), thereby potentially conflating the role of early life conditions,
migration patterns, and effects of destinations. We use the newly available
Mortality Disparities in American Communities (MDAC) dataset, which links
respondents in the 2008 ACS to official death records and estimate
consequential differences by method of aggregation; the mean absolute
deviation of the difference in life expectancy at age 50 measured by state of
birth versus state of residence is 0.58 (0.50) years for men and 0.40 (0.29)
years for women. These differences are also spatially clustered, and we show
that regional inequality in life expectancy is higher based on life
expectancies by state of birth, implying that interstate migration mitigates
baseline geographical inequality in mortality outcomes. Finally, we assess how
state-specific features of in-migration, out-migration, and non-migration
together shape measures of mortality disparities by state (of residence),
further demonstrating the difficulty of clearly interpreting these widely used
measures. |
